Add diced mango to a large bowl. To dice the mango, place it on its side on a cutting board. Cut down each side of the pit. With each cut piece, cut diagonal lines ¼” apart, without cutting through the peel. Turn the piece ¼ turn and repeat to create a checkered pattern. Use a spoon to scoop the mango pieces out, or pop the mango and use a knife to release the pieces from the skin.
To the mango in the large bowl, add the diced red pepper, onion, and jalapeno.
Squeeze lime juice over the mango mixture. Add cilantro, garlic, oil, cumin, and salt. Carefully toss to combine. Taste, and add salt if desired.
Rest for 30 minutes and serve.
Notes
Ingredient amounts may be altered to taste.
If making ahead, refrigerate in an airtight container for 2-3 days. For best quality, leave out the fresh tomato and avocado until just before serving.
